Hissing acid flows freely through subterranean tunnels. It's probably best that you don't breathe too deeply...
The prompt that started this cave map was "jumping puzzle." I began with the central tunnel and it's to-and-fro walkway, and then created the spaced pillars for some extra cruelty.
Each jump is about 10 feet at maximum, feasible to most athletic characters with a good run-up – but where will you get your run up once should you hesitate atop a platform? Throw in some enemies to break up movement and watch this map become your next BBEG.

This map also comes with a friendly 'Water' variant, in case you're interested in the jumping puzzle without the lethality! There are also some wild and wonderful variants in the Gold Pack that you can peek at below.
So, what monster would live here anyway? I'd love to hear your encounter ideas below! I'm thinking of acid-proof slugs that like to leave behind a slippery trail all over those platforms...
